Description

Technical Field

[0001] This application relates to port equipment, specifically to a lubrication device and a ship loader. Background Technology

[0002] The slewing bearing mechanism is a crucial component of port equipment such as ship loaders. It rotates the upper structure of the equipment to cover a wider area. For example, when the ship loader is not traveling along the track, the slewing bearing allows the boom and chute to be rotated back to the quayline, effectively improving loading efficiency and facilitating maintenance. Due to the dusty conditions at bulk cargo terminals, the slewing bearing is typically enclosed in a casing. The external gear ring of the slewing bearing requires frequent lubrication. If the drive gear and external gear ring are not properly lubricated, wear and tooth breakage can easily occur, posing safety hazards to port equipment such as ship loaders. However, traditional methods involve manually applying grease to lubricate the external gear ring of the slewing bearing, which is arduous, time-consuming, labor-intensive, and inefficient. Existing lubrication devices also suffer from manufacturing difficulties and poor lubrication effects, thus failing to meet the needs of automated terminal operations. Utility Model Content

[0003] The purpose of this application is to provide a lubrication device and a ship loading machine that are easy to manufacture and improve lubrication performance.

[0006] In one possible implementation of the first aspect described above, each second channel has a countersunk threaded hole at one end away from the center hole of the lubricating gear, and the plug is a screw plug that mates with the countersunk threaded hole.

[0007] In one possible implementation of the first aspect described above, each oil outlet and its corresponding second channel are located in the same radial plane of the lubrication gear and are inclined outward from the corresponding second channel toward the outside of the lubrication gear.

[0008] In one possible implementation of the first aspect described above, each tooth of the lubricating gear corresponds to two or more second channels arranged sequentially at intervals along the axial direction.

[0009] In one possible implementation of the first aspect above, the first channel includes: a vertical channel, which is coaxial with the main shaft and has a closed bottom, and an oil nozzle connected to the top of the vertical channel is provided at the top of the main shaft; and a plurality of radial channels, which are evenly distributed along the circumference of the main shaft and located at the lower end of the main shaft, with one end of the plurality of radial channels connected to the bottom of the vertical channel and the other end connected to each of the second channels.

[0010] In one possible implementation of the first aspect above, the diameter of the central hole of the lubricating gear is larger than the outer diameter of the main shaft. Two bearings for cooperating with the main shaft are provided in the central hole of the lubricating gear. The two bearings are arranged vertically. An oil storage space is formed between the outer wall of the main shaft, the inner wall of the central hole of the lubricating gear, and the two bearings. Each radial channel and each second channel are located between the two bearings and are connected to the oil storage space.

[0011] In one possible implementation of the first aspect described above, the bottom of the spindle is located inside the central hole of the lubrication gear and is locked by a locking member. The bottom of the lubrication gear is provided with an end cap for sealing the central hole of the lubrication gear, and the top of the lubrication gear is provided with a through cover for sealing the central hole of the lubrication gear. The through cover is provided with a first through hole for the spindle to pass through.

[0012] In one possible implementation of the first aspect described above, a seal for cooperating with the spindle is provided in the first through hole.

[0013] In one possible implementation of the first aspect described above, a horizontal mounting plate is provided on the bracket, a second through hole for the spindle to pass through is provided on the horizontal mounting plate, a slot and a baffle that cooperates with the slot are provided on the outer side of the upper end of the spindle, and the baffle is connected to the horizontal mounting plate by fasteners.

[0014] According to a second aspect of this application, a ship loader is provided, including the lubrication device described in the first aspect.

[0015] The above-mentioned technical solution of this application has at least one of the following beneficial effects:

A lubrication gear is provided on the main shaft, and a second channel corresponding to each tooth of the lubrication gear is provided on the lubrication gear. Each second channel is arranged radially along the lubrication gear and extends from its corresponding tooth tip surface to the center hole of the lubrication gear. A plug and an oil outlet are provided at the end of each second channel away from the center hole of the lubrication gear. The outlet of each oil outlet is located on the side wall of the tooth groove of the lubrication gear on one side of the second channel. The other end of the first channel is connected to the end of each second channel near the center hole of the lubrication gear. Therefore, it is not only convenient to process the second channel on the lubrication gear, but also convenient to maintain by plugging the end cap. The manufacturing process is simple. Moreover, the outlet of the oil hole of each second channel is located on the side wall of the tooth groove of the lubrication gear. As the lubrication gear meshes and rotates with the outer gear ring of the slewing bearing, it ensures that the viscous lubricating grease is more fully retained on the tooth profile surface of the outer gear ring. Then, during the meshing and rotation of the outer gear ring with the corresponding drive gear, the lubricating grease on the tooth profile surface is squeezed to form an oil film, which plays a lubricating role. It can lubricate the drive gear and the outer gear ring in a timely and effective manner, improve the lubrication effect, and prevent problems such as wear and tooth breakage of the outer gear ring. This reduces the safety hazards of port equipment such as ship loaders, extends the service life of the equipment, and can meet the needs of automated dock operations.

[0034] See Figures 1-6 The diagram schematically illustrates a lubrication device 100 provided according to an embodiment of this application, primarily used for lubricating the external gear ring 201 of the slewing bearing 200 of a ship loader, but also applicable to other port equipment with similar structures. The lubrication device 100 of this application may include: a bracket 110, a main shaft 120, and a lubrication gear 130.

[0035] The bracket 110 is used to be installed on the slewing platform 300 of the ship loader and located below the slewing platform 300. The main shaft 120 is installed on the bracket 110 in a vertical direction. The lubrication gear 130 is installed at the lower end of the main shaft 120 and is used to mesh with the external gear ring 201. The main shaft 120 can be connected by passing through the center hole of the lubrication gear 130. The main shaft 120 is provided with a first channel 121, and the lubrication gear 130 is provided with a second channel 131 corresponding to each tooth. Each second channel 131 is arranged radially along the lubrication gear 130 and extends from its corresponding tooth tip surface to the center hole of the lubrication gear 130. Each second channel 131 is provided with a plug 132 and an oil outlet 133 at one end away from the center hole of the lubrication gear 130. The outlet of each oil outlet 133 is located on the side wall (i.e. tooth profile) of the tooth groove of the lubrication gear 130 on one side of the second channel 131. Each oil outlet 133 is located on the same side of its corresponding second channel 131. One end of the first channel 121 is used to connect to the corresponding grease supply device, and the other end of the first channel 121 is connected to the end of each second channel 131 near the center hole of the lubrication gear 130.

[0036] It should be noted that the reference Figures 5-6 As shown, Figure 6 It shows Figure 5Partial cross-sectional views at points AA and BB, taking a ship loader as an example: the outer gear ring 201 of the slewing bearing 200 is fixedly mounted on the gantry 500 of the ship loader; the inner slewing ring 202 of the slewing bearing 200 is connected to the bottom of the slewing platform 300 of the ship loader; the inner slewing ring 202 is fitted inside the outer gear ring 201 and rotatably connected to the outer gear ring 201; the axes of both the inner slewing ring 202 and the outer gear ring 201 are aligned with the vertical direction; rollers can be installed between the inner slewing ring 202 and the outer gear ring 201 to ensure that the inner slewing ring 202... The external gear ring 201 rotates stably relative to the rotary platform 300, which is equipped with a drive device 400. The drive device 400 includes a drive motor 401, a drive shaft 402, and a drive gear 403. The drive motor 401 is mounted on the top surface of the rotary platform 300. The drive shaft 402 is arranged vertically. The output shaft of the drive motor 401 can be connected to the upper end of the drive shaft 402 through a coupling and a reduction gearbox (such as a planetary reducer). The drive gear 403 is located at the lower end of the drive shaft 402 and meshes with the external gear ring 201. There can be two drive devices 400, with two drive gears 403 symmetrically arranged on both sides of the external gear ring 201 to ensure more stable rotation.

[0037] When the rotary platform 300 needs to rotate, the drive gear 403 of the drive device 400 rotates and meshes with the external gear ring 201, causing the drive gear 403 to move along the circumference of the external gear ring 201, thus realizing the rotational motion of the rotary platform 300. At the same time, the lubrication gear 130 of the lubrication device 100 also meshes with the external gear ring 201, and the lubrication gear 130 moves together with the rotary platform 300. The corresponding grease supply device supplies lubricating grease to the lubrication device 100, and the lubricating grease passes through the main shaft 120 sequentially. The lubricating grease flows from the second channel 131 of the lubrication gear 130 and the oil outlet 133 of the second channel 131. As the lubrication gear 130 meshes and rotates with the outer gear ring 201 of the slewing bearing 200, the viscous lubricating grease is fully retained on the tooth surface of the outer gear ring 201. Then, during the meshing and rotation of the outer gear ring 201 with the drive gear 403, the lubricating grease on the tooth surface is squeezed to form an oil film, which plays a lubricating role, and can lubricate the drive gear 403 and the outer gear ring 201 in a timely and effective manner. In addition, the lubrication gear 130 of the lubrication device 100 can be set close to the drive gear 403, and the two lubrication gears 130 correspond one-to-one with the two drive gears 403. The two lubrication gears 130 rotate in opposite directions, so that the slewing platform can be lubricated in a timely and effective manner during both forward and reverse rotation, which is more stable, reliable and has a better effect.

[0038] Therefore, the lubrication device 100 of this application not only facilitates the machining of the second channel 131 on the lubrication gear 130, but also facilitates maintenance by plugging the end cap 132, making the manufacturing process simple. Moreover, the outlet of the oil hole 133 of each second channel 131 is located on the side wall of the tooth groove of the lubrication gear 130. As the lubrication gear 130 meshes and rotates with the outer gear ring 201 of the slewing bearing 200, it ensures that the viscous lubricating grease is more fully retained on the tooth surface of the outer gear ring 201. Then, during the meshing and rotation of the outer gear ring 201 with the corresponding drive gear 403, the lubricating grease on the tooth surface is squeezed to form an oil film, which plays a lubricating role. It can lubricate the drive gear 403 and the outer gear ring 201 in a timely and effective manner, improve the lubrication effect, and prevent problems such as wear and tooth breakage of the outer gear ring 201. This reduces safety hazards of port equipment such as ship loaders, extends the service life of the equipment, and meets the needs of automated dock operations.

[0039] In some embodiments, reference Figures 2-3 As shown, each second channel 131 has a countersunk threaded hole 134 at one end away from the center hole of the lubrication gear 130, and the plug 132 is a screw plug that mates with the countersunk threaded hole 134, such as an internal hexagonal plug. This not only ensures that the tooth tip surface of the lubrication gear 130 is flat, making the structure more compact and stable, but also facilitates the installation and removal of the plug 132, making maintenance more convenient.

[0040] In some embodiments, reference Figure 3 As shown, each oil outlet 133 and its corresponding second channel 131 are located in the same radial plane of the lubrication gear 130 and are inclined outward from the corresponding second channel 131 toward the outside of the lubrication gear 130. This ensures better oil delivery and improves the lubrication effect.

[0041] In some embodiments, reference Figure 2 As shown, each tooth of the lubricating gear 130 has two or more second channels 131 arranged sequentially along the axial direction. This ensures that the lubricating grease is sufficiently and evenly retained on the tooth profile surface of the outer gear ring 201, further improving the lubrication effect.

[0042] In some embodiments, reference Figure 2 , 4As shown, the first channel 121 includes a vertical channel 122 and multiple radial channels 123. The vertical channel 122 is coaxial with the main shaft 120, and its bottom is closed. A grease nipple 140, communicating with the top of the vertical channel 122, is located on the top of the main shaft 120. The grease nipple 140 is used to connect to a corresponding grease supply device. The multiple radial channels 123 are evenly distributed along the circumference of the main shaft 120 and located at its lower end. One end of each radial channel 123 communicates with the bottom of the vertical channel 122, and the other end communicates with each of the second channels 131. This allows for better delivery of lubricating grease.

[0043] Furthermore, the diameter of the central hole of the lubrication gear 130 is larger than the outer diameter of the main shaft 120. Two bearings 150 for cooperating with the main shaft 120 are provided in the central hole of the lubrication gear 130. The two bearings 150 are arranged vertically. An oil storage space 101 is formed between the outer wall of the main shaft 120, the inner wall of the central hole of the lubrication gear 130, and the two bearings 150. Each radial channel 123 and each second channel 131 are located between the two bearings 150 and are all connected to the oil storage space 101.

[0044] In other words, the main shaft 120 is relatively fixed, and the lubrication gear 130 rotates stably around the main shaft 120 through two bearings 150. The lubricating grease enters the oil storage space 101 evenly through the grease nipple 140, the vertical channel 122 and each radial channel 123 in sequence. The lubricating grease in the oil storage space 101 then enters each second channel 131 evenly. Thus, the oil storage space 101 can buffer and store the lubricating grease, ensuring better delivery of lubricating grease and higher safety and reliability.

[0045] In some embodiments, reference Figure 2 As shown, the bottom of the spindle 120 is located inside the central hole of the lubrication gear 130 and is locked by the locking member 170. The bottom of the lubrication gear 130 is provided with an end cap 180 for sealing the central hole of the lubrication gear 130, and the top of the lubrication gear 130 is provided with a through cap 190 for sealing the central hole of the lubrication gear 130. The through cap 190 has a first through hole (not shown in the figure) for the spindle 120 to pass through. The end cap 180 and the through cap 190 can be installed on the axial end face of the lubrication gear 130 using fasteners such as screws. The locking member 170 can be a locking nut, located below the two bearings 150. The top of the locking nut mates with the inner ring of the bearing 150 closest to it. A retaining washer can also be provided between the top of the locking nut and the inner ring of the bearing 150 closest to it to prevent the locking nut from loosening. A sealing member 191, such as a felt ring, for mates with the spindle 120 can also be provided in the first through hole to improve sealing. As a result, it is easier to operate, the structure is more stable, and it is easier to maintain.

[0046] In some embodiments, reference Figure 1 As shown, a horizontal mounting plate 111 is provided on the bracket 110. The horizontal mounting plate 111 has a second through hole (not shown) for the spindle 120 to pass through. A slot 124 and a baffle 160 cooperating with the slot 124 are provided on the outer upper end of the spindle 120. The baffle 160 is connected to the horizontal mounting plate 111 by screws or other fasteners. There can be two or more horizontal mounting plates 111 arranged vertically. The baffle 160 is located on the upper surface of the uppermost horizontal mounting plate 111. Slots 124 can be provided on both sides of the spindle 120, with the baffle 160 corresponding to each slot 124. This makes operation more convenient and ensures greater stability of the spindle 120.

[0047] A ship loader also provided according to an embodiment of this application includes the aforementioned lubrication device 100. Other components of the ship loader may employ corresponding mechanisms from the prior art, which will not be described in detail here.

[0048] Therefore, the ship loader of this application adopts the above-mentioned lubrication device 100, which not only makes the lubrication gear 130 easy to manufacture and maintain, but also ensures timely and effective lubrication of the drive gear 403 and the external gear ring 201, improves the lubrication effect, and is less likely to cause wear or tooth breakage of the external gear ring 201, thereby reducing safety hazards of port equipment such as ship loaders, extending the service life of the equipment, and meeting the needs of automated dock operations.

[0049] Based on the various embodiments of this application described above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0050] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of the appended claims.
